Prolonged exposure to manganese fume can cause Parkinson’s–like symptoms. • Gases such as helium, argon, and carbon dioxide displace oxygen in the air and can lead to suffocation, particularly when welding in confined
WebThe effects of cold working on metals are summarised below: (i) The grain structure is distorted and resistance to working keeps on increasing due to the lattice distortion. (ii) Residual stresses are set up in the metal which remains unless they are removed by subsequent heat treatment. WebArticle shared by: In metal forming, particularly in hot forming many metallurgical processes may take place concurrently. These include strain hardening, recovery, re-crystallization, etc. All these factors affect the yield strength. Therefore, it is important to know the extent of effect of each of these factors.
