Abstract Magnesium (Mg) alloys are the lightest metal structural material for engineering applications and therefore have a wide market of applications. However, compared to steel aluminum alloys, Mg lower mechanical properties, which greatly limits their application. Extrusion is one most important processing methods its alloys. effect such heterogeneous microstructure achieved at low temperat...

In this work, a novel solid-phase processing; namely, shear assisted processing and extrusion (ShAPE) was used to modify the microstructure of AZ31 magnesium alloy, which simultaneously improved corrosion resistance along with mechanical properties compared wrought alloys. A noble breakdown potential, higher polarization resistance, smaller film thickness after immersion observed ShAPE processi...

Abstract Al-Si wrought piston alloys can lack properties due to inefficient grain refining. A novel Al-Nb-B refiner was introduced some time ago, but has still not been assessed in industry for alloys. This paper describes the first trial of Al-Ni-B addition and its impact on full-scale manufacturing, structure, AA4032 products extruded with without billet homogenization. It is shown that Nb-B ...

Lightweight magnesium (Mg) alloys are being progressively incorporated into structural applications where weight reduction is an important design priority. Higher strength and better formability can be achieved by the development of new processing methods and new alloy composition, which entail a comprehensive understanding of the processing-microstructure-property relationship and deformation ...

Abstract A novel solid-state additive manufacturing (AM) process, friction stir deposition (AFS-D), provides a new pathway for additively repairing damaged nonweldable aerospace materials that are susceptible to induced thermal gradients within the microstructure. In this work, we quantify microstructural evolution and mechanical performance of an repaired AA7075-T651 (Al-Zn-Mg-Cu) via AFS-D pr...

The softening and strengthening contributions in pre-deformed aged Al–Mg–Cu alloys containing 3 wt.%Mg 0.5 wt.%Cu are evaluated by a combination of microscopy, mechanical testing modelling. A refined phenomenological model for the work hardening response, accounting separate effects recovery precipitation, is shown to be suitable an unambiguous determination precipitation contribution these all...

The present review article evaluates the research and progress status of Cu–Ni–Sn-based spinodal alloys focussed on methods technologies implemented to enhance properties cast Cu–Ni–Sn in industrial applications, particularly components such as bearings, bushings, propellers, impellers that find extensive demand marine automotive industry. introduces limitations employing copper-beryllium indus...
