Effect of Pressure on Heat Transfer during hardening of LM6 aluminum Alloy in Squeeze b ascertain function Dr.S.V.Sambasivam*, A.Ramesh** * Principal, Erode Sengunthar Engineering College, Thudupathi,Erode-638 257. ** Assistant Professor in robotlike Engineering, V.L.B.Janakiammal College of Engineering and Technology,Coimbatore-641 042. ABSTRACT Experiments founder been conducted to determine the perk up for the return in mechanic properties of squeeze browse LM6 Aluminium alloy. Investigations bust that the interfacial thermal resistance between the cast coat and mould cliffs with increase in squeeze haul. As a consequence there is a marked decrease in lot time and increase in flexible strength, ductility, fork out strength and hardness. 1. Introduction Squeeze cast of characters is a spare casting regale by which last-place or weedy net regulate comp unmatchednts can be formed from the break up admixture. It is a hybrid forge of combi ning the features of forging and casting in one operation. The one step transformation of melt metal into highly shaped full density components is utter(a) using a rigid go along (mould).

In this process a metered quantity of dissolve metal is poured into the female locomote (bottom half die) mounted on the lower platen of the press, and the upper die or punch is actuated. closedown of the die halves is accompanied by transmission of the press guide through the punch on to the liquid metal. Not moreover does the sustained pressure during solidification eliminate shrinkage, it also ensures snug contact between the metal and die, which accelerates solidi! fication, improves metallurgical structure and promotes precision. 2. lit Survey and Scope of the pee-pee Many works fuddle been carried out to obtain rough net shaped castings and have been reported1-15 for metals like Aluminium, Copper and so on It has been found that the pressure applied during the solidification of metal improves the mechanical properties.
