A form of radiant energy with extremely short wave length which has the ability to penetrate materials that absorb or reflect ordinary light. X-Rays provide a form of Non-Destructive testing.
Comparison of finished casting weight verses total weight of metal poured in a mold. A value expressed as a percentage indicating the relationship of the weight of a casting to the total composite of the casting and its gating system.
The ratio of yield strength to ultimate tensile strength.
A measure of the amount of mechanical stress a material can withstand before it permanently deforms.
