Figure 1: Principle of the LBM process Fundamentals and State of the Art Manufacturing of Rare Earth NdFeB Magnets Permanent magnets made of the material NdFeB are currently produced either by powder metallurgy or as composite materials made of magnetic particles and plastic.
Only LBM offers not only a small minimum structural size of the components, but also a good surface quality and the elimination of binder materials, whereby the maximum achievable parameters are only dependent on the magnetic alloy used.

Analysis of the reasons shows that under the optimum concentration of the explosion,methane almost completely react with oxygen.The rising ambient temperature on the one hand increases the internal energy of molecule,speeds the rate of molecular motion, increases the probability of collision between the molecules and accelerates the rate of explosion reaction;on the other hand,according to the gas state equation,the explosion in the volume container and ambient pressure remains unchanged, as the ambient temperature rises, the reaction will reduce the amount of methane-air mixture within the container material, thus affects the final explosion pressure changes. 3.

In this research work, an attempt has been made to study the weldability of AISI 304L using filler materials ENiCu-7 and ENiCrMo-3 by Gas Tungsten Arc Welding (GTAW) process.
Experimental The candidate material and the filler metals selected for the study are AISI 304L, ENiCu-7 and ENiCrMo-3 respectively; the chemical composition of the as-received AISI 304L sample and the filler wires are given in Table 1.0 Table 1.0 Chemical composition of the base and Filler Metals The as-received AISI 304L plate were sliced using wire-cut EDM process so as to obtain the samples with proper and accurate dimensions for welding.
