Microstructure formation mechanism during a novel semisolid rheo-rolling process of AZ91 magnesium alloy

Rheo-Cast Microstructure and Mechanical Properties of AM60 Alloy Produced by Self-Inoculation Rheo-Diecasting Process

Rheo-forming is becoming the choice for production of high quality parts with diminished defects and fine integrity. In this paper, the novel self-inoculation rheo-diecasting (SIRD) process, in which semisolid slurry is produced by mixing two precursory solid and liquid alloys and subsequently pouring them through a multi-stream fluid director, has been proposed. Microstructural characteristics...

Oxide Film and Porosity Defects in Magnesium Alloy Az91

Porosity is a major concern in the production of light metal parts. This work aims to identify some of the mechanisms of microporosity formation in magnesium alloy AZ91. Microstructure analysis was performed on several samples obtained from gravity-poured ingots in graphite plate molds. Temperature data during cooling was acquired with type K thermocouples at 60 Hz at three locations of each ca...

the effect of hot deformation on the microstructure of az91 magnesium alloy

due to the great variety of applications of magnesium alloys with superior mechanical properties, recent studies have been focused on the hot deformation behavior and microstructure of magnesium alloy castings. although there have been several recent investigations on the microstructure of wrought magnesium alloys after hot deformation, a limited number of studies have been conducted with regar...

Microstructure-sensitive investigation of magnesium alloy fatigue

Optimization and utilization of semisolid casting process for semisolid welding of Al-6061 alloy

Semisolid processing is one of the modern routes in sound and near net shape parts production.  Preparation of semisolid slurry using a cooling slope is increasingly becoming popular, primarily because of its simplicity in design and ease of control of the process. In this research, the microstructures of Al6061 semisolid alloy cast via a miniature cooling slope were investigated. The propertie...
