Austempered Materials for Powertrain Applications

Jun 15, 2012 · bending and/or contact fatigue strength, better wear resistance and enhanced dampening characteristics resulting in lower noise. Austempered materials have been used to improve the performance of powertrain components in numerous applications for a wide range of industries, from gears and shafts to clutch plates and crankshafts. Best Way to Improve Fatigue Resistance of a Bolted Joint The best way to improve fatigue resistance is to reduce the alternating stresses at the threads. There are three main ways of doing this:Assembly design, assembly tightening, and assembly security. The assembly design process provides an opportunity for improvement of the load distribution on bolted joints and to reduce the level of external

Best Way to Improve Fatigue Resistance of a Bolted Joint

The best way to improve fatigue resistance is to reduce the alternating stresses at the threads. There are three main ways of doing this:Assembly design, assembly tightening, and assembly security. The assembly design process provides an opportunity for improvement of the load distribution on bolted joints and to reduce the level of external stresses supported by each joint. Enhanced Fatigue and Durability Properties of Natural properties. Therefore, new methods to improve the fatigue resistance of rubber materials and accurately predict their fatigue life are always necessary. The type, content, and dispersion of nanollers have a signicant inuence on the microstructural, static, mechanical, and dynamic fatigue properties of rubber composites [7,8]. Enhanced fatigue crack growth resistance at elevated The fatigue crack growth behavior of TiC/Ti-alloy composite was examined at 450 °C and compared to the room-temperature behavior. Contrary to the temperature-dependent fatigue crack growth behavior of the monolithic alloy, fatigue crack growth resistance of the composite was improved at the elevated temperature. At 450 °C, the fatigue threshold of the composite was found to be 50 Pct higher

Enhanced fatigue crack growth resistance at elevated

The fatigue crack growth behavior of TiC/Ti-alloy composite was examined at 450 °C and compared to the room-temperature behavior. Contrary to the temperature-dependent fatigue crack growth behavior of the monolithic alloy, fatigue crack growth resistance of the composite was improved at the elevated temperature. At 450 °C, the fatigue threshold of the composite was found to be 50 Pct higher Evaluation of the Surge and Fatigue Resistance of PVC and Fatigue is associated with the repetition of such events, where the fluctuatrons in pressure cause a loss in the long-term strength of the pipe material. Because it was believed that the combined effect of over-pressurization from surge and loss in properties caused by fatigue could have serious implications on the lifetimes of PVCu pipelines Improved Materials and Enhanced Fatigue Resistance for Improved Materials and Enhanced Fatigue Resistance for Gear Components.

Improved fatigue resistance in Gs-deficient and aging

Supporting the hypothesis that the enhanced fast-to-slow-fiber-type switch in soleus muscle of aging MGsKO mice may have a benefit by functionally compensating for the decreased force production, aging MGsKO soleus muscles exhibited higher resistance to fatigue with better recovery than that of age-matched controls (Fig. 9). Improved fatigue resistance of gradient nanograined Cumetals can be markedly improved via gradient nanostructures with the presence of compressive residual stress [31,39e41]. However, application of such strategies to improve fatigue damage tolerance and failure resistance in both high-cycle and low-cycle regimes has thus far remained unexplored. Here we present a unique experimental study of the effect of LOWTEMPERATURE AUTOFRETTAGE:AN IMPROVED Abstract It is shown that autofrettage at low temperatures is superior to autofrettage at room temperature in enhancing the fatigue resistance of thickwalled tubes against pulsating internal pressure. The physical reason is based on the wellknown temperature dependence of the mechanical behaviour of metals and alloys which generally exhibit an enhancement of both the yield stress and
