Web13 feb. 2024 · Stress relief heat treatment, control of the heat-treating process, and alloy selection are other methods of controlling residual stresses. Since metal yield strength decreases as its temperature increases, metals can be stress relieved by heating to a temperature where the yield strength of the metal is the same or less than the magnitude …
WebIt is generally preceded by a solution heat treatment. For steel, the temperature may be somewhere between 450-740 degree C, an aluminium alloy would be aged at between 100-200°C. Longer times and/or higher temperatures result in an increase in size of the precipitate and a reduction in both hardness and strength. Stress relief Web26 mrt. 2024 · In cases where annealing is not suitable, stress-relief treatment can be performed by heating the parts to a temperature of 230~370℃, holding the temperature, …
WebLimit the ratio of the large feature to the small feature. Add stress-reducing holes at the end of slits, sharp angles, or cracks to relieve high-stress concentrations. Refer to stress concentration charts to understand when you are in a region of diminishing returns concerning radius size. WebMeta-Lax is a proven substitute for 80% to 90% of heat-treatment stress relief in metal-working applications. It improves the inconsistencies of the previous resonant-vibration technology by using more efficient, more consistent "sub-harmonic" vibrational energy, which is the optimum vibration stress relief frequency.
