Work of fracture

Have to give a spiel on materials and I am looking for some figures (however
vague) on the effect of heat treatment on this particularly - work of
fracture vs yield. The most useful materials for examples being:
4130 steel
2024 aluminium
6061 aluminium
7075 aluminium

Googling doesn't seem to give any useful links

Any ideas?
