Graphitization Behavior of a Spray Formed Ultra High Carbon Steel during Hot Rolling

Abstract: The effect of hot rolling parameters on graphitization of a spray formed ultra high carbon steels(UHCSs) was described The number of graphite stringers and graphite area fractions increased with the increase of rolling reduction Graphite stringers nucleated at small pores and grew by carbon diffusion from adjacent austenite during hot rolling Alloy contents, pores and hot deformation atγ+Fe3C phase range are the key factors for graphitizationThe graphite stringers of UHCSs have little effect on tensile strength, but reduce the ductility at room temperature

Research on Properties of High Speed Steel Prepared by Spray Forming

Abstract: The microstructure and some mechanical properties of high speed steel(HSS) T15 preform made by spray forming were researched.The result indicated that the high-quality perform of HSS T15 exhibited high-density,refined grains and segregation-free macrostructure.The average density of perform before heat treatment(HT) is 8.208g/cm3 and three-point bending strength reaches 1860 MPa.All of them show that spray forming is an appropriate technics to fabricate high-property HSS.But some local porosities were found in HSS perform through scanning electron micrograph(SEM).In order to improve the properties more,some hot-machining to HSS preform made by spray forming.

Experimental and mathematical modeling of metal spray forming process

Abstract: The metal spray forming process was examined using mathematical simulation and verified through the prototyping evaluation at Baosteel's test and development facilities. The mathematical model comprised of four sections, including jet gas flow in the deposition chamber; single droplet behavior along its trajectory path; probability and statistical analysis of droplet mass behavior, and forecast of the shape and temperature distribution of the billet during the spray forming process.

Process for manufacturing AL-Si alloys for use in vehicle propeller shafts

Abstract: A process for manufacturing an Al—Si alloy for use in a vehicle propeller shaft is provided. The Al—Si alloy manufacturing process includes the steps of heating and melting Al—Si alloy where Si contains 13-40 weight percentage (wt %) of the whole alloy, to thereby prepare melt, maintaining the melt at 700-900° C. and then spraying an high pressure inert gas to the melt and rapidly solidifying the same to thereby obtain a forming body, and extruding the forming body at 400-550° C. The physical properties of the Al—Si alloy manufactured by a spray forming process is at least similar to that of the vehicle propeller shafts which have been already known, and also spotlighted as new alloy compositions which can replace the conventional propeller shaft material.
