Heat Treating Overview Heat treating,as the name implies,is a series of treatments in which heat is used to alter the properties of a metal or alloy.Because time at temperature is also important,heat treatment can be further defined as a series of time-temperature treat-ments.Heat treatments are used for a variety of purposes,thePost-Weld Heat Treatment Case StudiesWhen a thermal stress relief treatment is employed to reduce residual stresses,other important properties must be taken into account.The micro-structure,tensile and impact strength are among the properties affected by the Stress relief treatment.A post weld heat treatment at 1040 cylindrical tanks Stress relief heat treatment#176; C 1090 cylindrical tanks Stress relief heat treatment#176; C,spheroidizes the ferrite present in type 347 SS

Heat Treating of Copper and Copper Alloys

Slow heating provides a measure of stress relief and minimizes non-uniform temperature distributions,which lead to thermal stress.Using a high stress-relieving temperature for a short time is generally considered best for keeping processing time and cost to a practical minimum,even though there is usually some sacrifice in mechanical properties.Heat Treating of Aluminum Castings Theat treatment improves mechanical properties to a large degree,stabilizes the castings and usually results in a slightly lower tensile and yield strength but an increased elongation value compared to the T6 series of heat treatments.Stress Relief and Annealing TS Condition Stress relief and annealing can be used to remove stressesFatigue Properties of a Titanium Alloy (Ti-6Al-4V and cooling rates,100 MPa) [2].The stress relieving heat treatment used was 5 h at 650 cylindrical tanks Stress relief heat treatment#219; in air followed by furnace cooling.The literature suggested that this heat treatment would lead to full stress relief [4].This stress relief cycle was chosen to achieve full stress relief
