Various processing methods exist for applying agitation to a molten metal during solidification to obtain metal slurries suitable for semi-solid metal processing. . In this paper, a new technique to achieve semi-solid metal structure using agitation during solidification is reported. The technique applies a new medium and means to efficiently create semi-solid metal structures. The results of a systematic study showing the feasibility and the necessary conditions to achieve the structure are discussed.

The needs for high-strength and light weight structural materials have increased in automotive and aerospace structure applications. The semi-solid processed light alloys inherently offer the opportunity to produce high integrity components for these requirements. Various processing methods exist for applying agitation to a molten metal during solidification to obtain metal slurries suitable for semi-solid metal processing. In this paper, a new technique (Cup-Cast method) to achieve semi-solid metal structure using agitation and direct spherical growth during solidification is reported. Cup-Cast method is the most quick and simple semi-solid processing route which semi-solid slurry would be prepared just by pouring molten metal into a metallic cup. In this study Cup-Cast method was introduced and effect of process parameters on micro-structural characterization of slurry prepared by this method was investigated.

Minimum Heat

Semi solid metal processing has numerous technical and economic advantages, such as viscous, non-turbulent flow (thus no air entrapment during casting), ability to fill ultra-thin sections (thus reduced part weight), little solidification shrinkage in the die (thus little or no porosity), minimum heat imparted to tooling (thus long tool life) and good response to T-5 aging (thus reduced heat treating costs). Still, SSM has never achieved a prominent position in the field of light metals casting Why? Perhaps the reason was largely the down economy of recent years and SSM will yet emerge with the prominence once expected of it.

The One

The birth of Semi-Solid Metal Forming (SSM) or as it has now come to be widely known, Thixoforming, is a typical case of development of a technological innovation. Serendipity, stroke of luck, call it what you may, the beginning of SSM is based on an almost accidental discovery by a student carrying out a series of meticulous experiments. On the one hand, some technological failures have contributed to the lack of success across the board for SSM technologies. On the other hand, the ‘long childhood’ of the resulting technology or the process of moving from ‘Innovative Idea to Market' has been largely the result of difficult and in hindsight sometimes wrong managerial decisions, occasional personality clashes, patent rights and at times unavoidable all out business 'warfare'. Of course, hindsight is beautiful but unfortunately it always comes after the event. However, if one looks carefully at some of the notable successes of SSM forming one can discern that the problems were more on the human scale; people failures rather than technology failures. This paper aims to bring out some of these points by outlining the historical development of Thixoforming.
