A Comparison of Thixocasting and Rheocasting
A Comparison of Thixocasting and Rheocasting Stephen P. Midson The Midson Group, Inc. Denver, Colorado USA Andrew Jackson Arthur Jackson & Co., Ltd. Brighouse UK Abstract The first semi-solid casting process to be commercialized was thixocasting, where a pre-cast billet is re-heated to the semi-solid solid casting temperature. Advantages of thixocasting include the production of high quality components, while the main disadvantage is the higher cost associated with the production of the pre-cast billets. Commercial pressures have driven casters to examine a different approach to semi-solid casting, where the semi-solid slurry is generated directly from the liquid adjacent to a die casting machine. These processes are collectively referred to as rheocasting, and there are currently at least 15 rheocasting processes either in commercial production or under development around the world. This paper will describe technical aspects of both thixocasting and rheocasting, comparing the procedures used to generate the globular, semi-solid slurry. Two rheocasting processes will be examined in detail, one involved in the production of high integrity properties, while the other is focusing on reducing the porosity content of conventional die castings. Key Words Semi-solid casting, thixocasting, rheocasting, aluminum alloys 22 / 1 Introduction Semi-solid casting is a modified die casting process that reduces or eliminates the porosity present in most die castings [1] . Rather than using liquid metal as the feed material, semi-solid processing uses a higher viscosity feed material that is partially solid and partially liquid. The high viscosity of the semi-solid metal, along with the use of controlled die filling conditions, ensures that the semi-solid metal fills the die in a non-turbulent manner so that harmful gas porosity can be essentially eliminated. -

Monte Carlo Stock
Gun Stocks STOCK DESIGN AND STOCK STYLE Types of Gun Stocks A gunsmith requires a basic understanding of stock function prior to becoming a stock maker. A rifle stock, in function, is nothing more than a segment of wood, fiberglass, plastic, or other material shaped to support the rifle’s barrel and action. It also functions to conform to the shooter’s body so the shooter can control the firearm. That’s the mechanical side of it. However, arms lovers the world over consider a stock much more than a mechanical device. They think of a gun stock as a work of art and function (Figure 1). As a prospec- tive gunsmith, we hope this is your position. FIGURE 1—Notice the attractive oak-leaf pattern on this Bishop-III stock. (Photo courtesy of Reinhart Fajen, Inc.) Stocks can be built in a multitude of styles with a stock shape to fit everyone. Even factory rifles come in a wide variety of stock styles. Factory stocks, incidentally, have come a long way and can be considered quite good today, although cer- tainly not in the realm of a custom-made stock. Figure 2 shows a gun stock labeled with its proper nomenclature. 1 FIGURE 2—Become familiar with the names of the parts of a gun stock. Early Stock Design Turning the pages of gun history to an earlier time reveals that the first stocks well known to American shooters had a great deal to do with contemporary stock designs. However, such muzzleloader stocks left a lot to be desired. -

Development of Guidelines for Warm Forging of Steel Parts
Development of Guidelines for Warm Forging of Steel Parts THESIS Presented in Partial Fulfillment of the Requirements for the Degree Master of Science in the Graduate School of The Ohio State University By Niranjan Rajagopal, B.Tech Graduate Program in Industrial and Systems Engineering The Ohio State University 2014 Master's Examination Committee: Dr.Taylan Altan, Advisor Dr.Jerald Brevick Copyright by Niranjan Rajagopal 2014 ABSTRACT Warm forging of steel is an alternative to the conventional hot forging technology and cold forging technology. It offers several advantages like no flash, reduced decarburization, no scale, better surface finish, tight tolerances and reduced energy when compared to hot forging and better formability, lower forming pressures and higher deformation ratios when compared to cold forging. A system approach to warm forging has been considered. Various aspects of warm forging process such as billet, tooling, billet/die interface, deformation zone/forging mechanics, presses for warm forging, warm forged products, economics of warm forging and environment & ecology have been presented in detail. A case study of forging of a hollow shaft has been discussed. A comparison of forging loads and energy required to forge the hollow shaft using cold, warm and hot forging process has been presented. ii DEDICATION This document is dedicated to my family. iii ACKNOWLEDGEMENTS I am grateful to my advisor, Prof. Taylan Altan for accepting me in his research group, Engineering Research Center for Net Shape Manufacturing (ERC/NSM) and allowing me to do thesis under his supervision. The support of Dr. Jerald Brevick along with other professors at The Ohio State University was also very important in my academic and professional development.
