Positron annihilation in shock loaded low-alloyed MnSi steel

摘要: The strengthening of metals and alloys by shock waves has been actively researched for the past three decades. It demonstrated that impulse loading, using explosive waves, strongly influences strength a variety alloys. As result loading an increase in hardness or tensile reduction ductility shown. These changes tend to be most significant at lower pressures. Shock higher pressures ultimately leads saturation'', i.e., pressure is reached when there little change mechanical behavior with any additional pressure. Microstructural examination had led various researchers conclude observed after are due dislocation density introduction twin (or) martensite. purpose present study investigate influence on residual low-alloyed Mn-Si steel elucidate defect structure positron lifetime technique.
