The higher the astm grain-size number, the coarser the grain is. a)-true b)-false

Draw the engineering stress-strain curve for (a) bcc; (b) fcc metals and mark important points.

Describe one experiment in which the glass transition temperature and melting temperature of a totally amorphous thermoplastic material can be determined. show the relevant experimental results in a diagram which should be properly annotated with the two temperatures clearly marked. what is likely to happen to the curve in the diagram if the amorphous polymer is replaced by a thermosetting type?
