SELECTION OF DIE MATERIALS AND SURFACE TREATMENTS …
www.forging.orgAfter the dies are tempered the “initial” room temperature hardness can be determined. During forging, as the die surface is subjected to high temperature, the hardness of the die decreases. Even if the initial hardness for a material is high, if the hardness drops down as the temperature is increased then the dies are favourable.

Determination of water hardness from common water …
dept.cord.eduWater hardness from drinking water appears to not be significantly different than tap water. Atomic absorbance is a fast, efficient way to determine water hardness and is an effective alternative to traditional titration methods. Introduction Water hardness is determined by measuring the total concentration of magnesium
