Abstract Applying additive manufacturing (AM) technologies to the fabrication of aluminum automotive components, with an optimized design, may result in improved vehicle light weighting. However, post-process heat treatment such alloys has be customized for particular AM microstructure. The present study is aimed at investigating effect different treatments on microstructure, hardness and resid...

The change of the surface relief associated with stress-induced epsilon martensite before and after the reverse transformation in an Fe-33%Mn-6%Si alloy (Msz264K) has been investigated. The permanent strain of a 2.7% tensile-strained specimen was 1.1% after the reverse transformation. In this specimen, a large part of surface relief still remained after heating to 623K (above Af). When five tra...

A rapidly growing literature on the financing of distressed companies finds that troubled firms often secure relief from stress through asset restructuring, capital restructuring, or both. However, none of the earlier corporate distress restructuring studies have focused on the centrally important commercial banking industry which has been one of the most financially distressed industries of th...

At present, great progress has been made in the prediction of undercompaction and fluid expansion overpressure. However, recent years, field frequently encountered pressure relief-type Different from primary overpressure, such as expansion, this type overpressure belongs to secondary which a certain concealment response seismic velocity logging data. Based on this, geological analysis model was...

The stress relief of tetrahedral amorphous carbon (ta-C ) films by post-deposition thermal annealing was investigated. The films were subjected to rapid thermal annealing (RTA) for 2 min and conventional furnace annealing (CFA) for 30 min. In both cases, the films were annealed in vacuum with argon (4×10−2 Torr) at successive higher temperatures ranging from 500 to 800°C. It was found that anne...

Background & aim: Women experience various changes in their transition into motherhood and feel stressed while facing new challenges in this period. High levels of stress may prevent mothers from realizing their maternal role. In this study, we aimed to explore the effects of training on the stress of primiparous mothers. Methods:In this quasi-experimental intervention, 100 pregnant women were ...
