Ats 34 and 154 Cm Stainless Heat Treat Procedure
ATS 34 AND 154 CM STAINLESS HEAT TREAT PROCEDURE This is an oil hardening grade of steel which will require oil quenching. The oil should be a warm, thin quenching oil that contains a safe flash point. Olive oil has been used as a sub stitute. As a rule of thumb, there should be a gallon of oil for each pound of steel. For , warming the oil before quenching, you may heat a piece of steel and drop it in the oil. 1.) Wrap blades in stainless tool wrap and leave an extra two inches on each end of the package. (This will be for handling purposes going into the quench as described below.) We suggest a double wrap for this grade. The edges of the foil should be double crimped, being careful to avoid hav ing even a pin hole in the wrap. 2 . ) Place in the furnace and heat to 1900"F. After reaching this temperature, immediately start timing the soak time of 25-30 minutes. 3.) After the soak time has elapsed, very quickly and carefully pull the package out with tongs~ place over the quench tank and snip the end of the package allowing the blades to drop into the oil. You should have a wire basket in the quench tank for raising and lowering the blades rather than have them lie s till. Gases are released in the quench and would form a "trap" around the steel unless you keep them movi~g for a minute or so. *IMPORTANT--It is very important that the blades enter the oil quench as quickly as possible after leaving the furnace ! Full hardness would not be reached if this step is not followed. -
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. -

This is typically done in power systems by twisting or weaving the wires, following one of several patterns. Though, at radio frequencies, wire dimensions must scale down by as much as 1000 times in order to achieve the same effects. This project decomposes the problem into two main categories; the manufacturing of micron scale wires and the manipulation of these wires in order to form a twisted bundle. -

Conventional Deep Drawing Vs Incremental Deep Drawing
MED, JNTUH August 2018 CONVENTIONAL DEEP DRAWING VS INCREMENTAL DEEP DRAWING A. Chennakesava Reddy Professor, Department of Mechanical Engineering JNTUH College of Engineering, Hyderabad 1. Conventional Deep Drawing Process: Deep drawing is a sheet metal forming process in which a sheet metal blank is radially drawn into a forming die by the mechanical action of a punch. It is thus a shape transformation process with material retention. The process is considered "deep" drawing when the depth of the drawn part exceeds its diameter. This is achieved by redrawing the part through a series of dies. The flange region (sheet metal in the die shoulder area) experiences a radial drawing stress and a tangential compressive stress due to the material retention property. These compressive stresses (hoop stresses) result in flange wrinkles (wrinkles of the first order). Wrinkles can be prevented by using a blank holder, the function of which is to facilitate controlled material flow into the die radius. Figure 1: Example of deep drawn part. Figure 2: Conventional deep drawing process. The total drawing load consists of the ideal forming load and an additional component to compensate for friction in the contacting areas of the flange region and bending forces as well as unbending forces at the die radius. The forming load is transferred from the punch radius through the drawn part wall into the deformation region (sheet metal flange). In the drawn part wall, which is in contact with the punch, the hoop strain is zero whereby the plane strain condition is reached. In reality, mostly the strain condition is only approximately plane.
