SUMMARY

This discussion focuses on techniques to strengthen commercially pure aluminium, mild steel (Fe-0.2%C), and commercially pure titanium (HCP metal). For aluminium, rolling followed by normalizing is recommended. Mild steel can be strengthened by forming martensite through heat treatment, followed by tempering or directly forming lower bainite. For titanium, methods include cold or hot working, as well as surface-hardening techniques like shot peening, acknowledging that titanium does not work harden as effectively as steel.

PREREQUISITES
  • Understanding of heat treatment processes, specifically quenching and tempering.
  • Knowledge of phase transformations in metals, particularly martensite and bainite formation.
  • Familiarity with cold and hot working techniques in metallurgy.
  • Awareness of surface-hardening methods, including shot peening.
NEXT STEPS
  • Research the heat treatment process for Fe-0.2%C mild steel, focusing on martensite and bainite formation.
  • Explore the effects of alloying elements on the strength of commercially pure aluminium.
  • Investigate the principles of cold and hot working in titanium alloys.
  • Learn about the shot peening process and its impact on the surface hardness of titanium and its alloys.
USEFUL FOR

Metallurgists, materials engineers, and anyone involved in the processing and strengthening of metals, particularly those working with aluminium, mild steel, and titanium alloys.

Using furnace and a rolling mill, how to strengthen these?
(i)Commercially pure aluminium
(ii) Fe-0.2%C (mild steel)
(iii)Commercially pure Titanium (HCP metal; 2 methods can be used)

How to strengthen these?
For (i), is that just roll it and then normalise it?
For(ii), forming martensite and then temper it or should be forming lower banite directly?
For(iii), again rolling? unlikely...

I am really nore sure about these...could anyone kindly help?
 
Engineering news on Phys.org
1) Add alloying elements or strain harden.
2) Heat to autenitic range and quench to martensite.
3) Since alpha alloys are non heat treatable, some form of cold or hot working (not quite sure on that one)
 
(iii)I've heard of surface-hardening of Ti and Ti-alloys by shot peening. I imagine rolling will work too but I do believe Ti does not work harden as much as most steels.
