Cryo treating blocks?

i'm nuts enough to type it all out, if i'd copied it, the spelling and grammar would be so much better, and way fewer words would have been used. year 10/11 school materials science...
chrystaline solids, dislocations in chrystaline structure why alloying works in respect to changeing properties, work hardening etc etc hopefully enough to give the gist...mind its 25 years since i had to stand on ceremony and get the eager minds to engage in something more than personal stereos, gangsta rap, extra long home rolled smokes, and who they were going thump next.

I'm a bit rusty

Sounds like your education system is much better over in the UK than here in the USA at least pertaining to these subjects. I didn't learn about materials science to this level until I started pursuing my engineering degree at university. It's a damn shame, so much time in American grade school is wasted on busy work or useless subjects no one cares about, and they wonder why students don't stay engaged and end up losing interest. Hell I hated school myself until I went to university, it was a frickin joke. The grade schools I went to were even considered better-than-average! But when the average is almost 30th in the world... oof I'm not looking forward to figuring out what I'm going to do for education when I have children.

The articles linked in here also give excellent explanations of how and why the cryo process works. The NitroFreeze one is perfect.
