A coil of sheet metal is taken to a furnace & annealed ,in order to improve its ductility.It is found ,however,that the sheet has a lower limiting drawing ratio than it had before annealin g .Explain why this has occured?

Sorry Miami enjoy your championship…just a few quotes from around the country………….Note: I’m not saying I agree with these perspectives … but here’s a very fair sampling of the e-mails that drifted into my mailbox on Sunday night and Monday morning.

I do solemnly swear, this 19th day of June, 2006 that I will never watch an NBA game again. Everyone is supposed to say what a great game that was with a straight face? At least the WWE has the grace to give you a wink. If watching a man in a flak jacket and thigh pads repeatedly throw himself into defenders to draw foul calls is what passes for “competition,” or better yet watching said man hit layups because no one can breathe on him, I believe I can live without [it]. Why would anyone follow a “sport” that employs Dick Bavetta and Stu Jackson? All that was missing was David Stern running onto the court with a steel chair, ABC execs in tow. Bill Simmons, I name thee prophet. It went down exactly as you said it would.

Twenty-five free-throw attempts is nonsense, not even MJ would have gotten some of those foul calls. And I’m not just saying this because I’m a bitter Pistons fan. Sixty-year-old officials should not be officiating 20-something-year-old professional athletes.

Have you ever, I mean EVER, seen a guy get more calls than Wade in Game 5? As staggering as it is to even think it, much less say it out loud, this surpasses the level of calls Jordan used to get in the playoffs. Simply AMAZING. I am a die-hard NBA fan, and I understand and accept the whole “stars get calls” factor, but this is an insane new level. Every time Wade falls down (even if not touched) he gets a call. You called it in your preview, the refs were gonna give some games to Miami, and they did.

Please admit to everyone that the treatment Dwyane Wade is receiving is absolutely absurd. The final play in Game 5 summed it up: He commits a backcourt violation, pushes off on Terry, then goes wildly to the bucket and gets bailed out on a phantom foul call. Is what the NBA has to do to create its star of the future?

I watch very little NBA basketball; however, as the playoffs have been playing out, I have found myself watching more and more games, becoming more interested. Then comes the Finals and I feel like I am watching pro wrestling, except I can fool myself into thinking those matches aren’t fixed. At least it makes the NBA the easiest sport to gamble on.

I want to say something about Dwayne Wade, but I fear I may get called for a foul.
– Warren, Ludington, Mich.

Unfortunately you were right that the NBA finals could come down to the officials. David Stern would rather choke to death on his own vomit than hand Mark Cuban the trophy. It’s clear he instructed the refs to take an active interest in the outcomes of the games. Every time Wade drives the lane the refs call a foul on whoever is closest.
– Jeff, Baltimore

After witnessing the Game 5 debacle, I am absolutely convinced that Stern is trying to fix the Finals for D-Wade and the Heat. Stackhouse’s suspension, Dirk’s phantom foul in OT, and then Joey Crawford’s inexplicable call for a Mavs timeout — it all adds up too perfectly. This could be a conspiracy as far-reaching as Watergate. I can already imagine the inevitable ESPN movie, “All The Commissioner’s Men,” where a stubborn, upstart young sports columnist brings down Stern and the entire NBA hierarchy. So, Simmons, the only question is: Will you be our Bob Woodward?
– Robert P., Topeka, Kan.

All the comparisons between Wade and Jordan need to stop right now. There’s no way Jordan would have gotten that call in the final seconds of Game 5.

I have induction bending machine , after bending the pipes the yield drop too much and after heat treatment may be increased but not to the normal values before bending

< My reference specifically refers to heat treatment of steel for strength (not annealing) >

I’m a designer currently taking a metallurgy class and I have little experience with heat treating parts I’ve designed (none to be exact). I could discuss with you all day about what’s going in the microstructure of metals but we’ve failed to talk about real world applications.

My question is: I assume (generally) parts are heat treated after working. If so, what happens to the tolerances?

Logic tells me to rough machine all the less functional dimensions of my part then heat treat. Afterward (once the part has been hardened) machine the more critical dimensions such as slip fit or press fitting features. If so, how is this done? grinding? tungsten carbide tools? (I have no idea I’m only speculating).

Also, If anyone can direct me to information on Metallurgy AND how’s it’s applied to real world fabrication processes it would be appreciated.

Thank you in advance

Hey all,

Last week I went to Mauritius for my holidays, and there I opted to do a ‘relaxer’ treatment in order for my hair to become straighter. As I was really new to it, I didn’t really realise the precautions I had to take after..

So unknowingly, I used a blowdryer and starightened my hair a couple of times during the past week and also swam in the sea… at the time – some hair were falling out, but I thought it was just a common thing as I was straightening my hair/etc…

Now having returned back to the UK, I’m beginning to notice my hair falling out bit my bit (just by passing my hand through my hair/washing it/sleeping/etc..)… And I’ve been reading up on the ‘relaxer’ treatment, with most of the articles stating I need to use a conditioner and avoid heating equipment..

So for the past two days, I’ve been using a moisturising conditioner and applying coconut oil in order to keep my scalp hydrated.. but the hair is still falling out.. and its making me paranoid that I may become bald?!

Any helpful advice and tips on how to prevent my hair falling out will be greatly appreciated.. Thanks!

Heat treatment is continuous process and steel is under eutectoid stainless steel with 0,1 mm thickness.
