Vitrolite is a glass ceramic with high strength, low porosity/high density and thermal shock tolerance. Technical Specifications. One is the maximum stress that the material can endure before "failure" occurs. Material: Solder Type: Tension: Shear: R m [psi] R ms [psi] Low strength steels (eg. In brittle materials the ultimate tensile strength is close to the yield point, whereas in ductile materials the ultimate tensile strength can be higher. Yield strength is the term used to refer to an indication of the maximum stress that can be developed in a substance without causing it to plastically deform. A few materials start to yield, or flow plastically, at a fairly well-defined stress (upper yield point) that falls rapidly. The Shear strength of a material under pure shear is usually 1/3 (0.577) times its tensile yield strength in case of Von mises criterion and 0.5 times its tensile yield strength in case of Tresca criterion. Ultimate strength describes the maximum amount of stress a metal can endure. Silver metal in its pure state has a brilliant white metallic lustre and it is a little harder than gold and is very ductile and malleable. Overall, yield strength decreases as porosity increases. Braze Filler temperature operation range. 1. The customary silver solder strength ranges from 40000 to 70000 pounds per sq inch (psi). Fatigue strength is the ability of a material to resist fatigue failure. Strain hardening, strain rate, the temperature of the metal and hydrostatic pressure will affect the value of yield strength.
