Abstract
With reference to imminent emissions regulation, the temperature is presumed to elevate in engines exhaust manifolds. To consider the present material in the manifolds, it’s necessary to study the performance of the material in the working temperature. In designing part for increase life, important material characteristics to be noted, as like creep, corrosion by oxidation and fatigue resistance. Alloys are considered for improving these material properties in exhaust gases at high temperature. In this present study, analysis of D5S is observed experimentally which is used for evaluating the damage mechanism of exhaust manifolds at variant temperature and strain amplitude. Mechanical properties are examined physically by optimizing the method of uniaxial stress-strain testing and low-cycle fatigue testing with different temperature range from 300 °C to 800 °C. Behavior of the material, experimentally analyze with these cyclic softening and cyclic hardening properties. Concisely, life cycle of material D5S confers during fatigue testing. Ni-resist D5S at high temperature, reduction in fatigue life is observed during transition from elastic part to plastic part under strain dominance. In addition, the results are achieved from low-cycle fatigue experiments lead towards the selection of rank material for these applying conditions.
