Title: Innovations of Ka Ram Lim
Introduction
Ka Ram Lim is a notable inventor based in Changwon-si, South Korea. He has made significant contributions to the field of materials science, particularly in the development of high-entropy alloys and advanced blow molding devices. With a total of three patents to his name, Lim's work showcases his innovative approach to solving complex engineering challenges.
Latest Patents
One of Lim's latest patents is focused on a high-entropy alloy and the method for producing it. This high-entropy alloy exhibits ultra-high strength and high hydrogen embrittlement resistance due to the formation of a microstructure at low strain. The production method involves annealing and homogenizing an initial alloy material at temperatures between 1000 to 1200°C for 1 to 24 hours, followed by rolling the material into a rod at cryogenic temperatures of -100 to -200°C. This process results in a high-entropy alloy characterized by intersecting twins and secondary fine twins within the microstructure. The alloy composition includes cobalt, chromium, iron, manganese, and nickel, each ranging from 5 to 35% by weight.
Another significant patent by Lim is a blow molding device capable of continuous processing. This device includes a heating unit designed to heat a molding material and molds that shape the material. The heating unit features an infrared lamp that emits infrared rays, a reflective mirror to concentrate these rays, and a light transmitting body that directs the concentrated rays to the molding material. The molds then utilize gas pressures to mold the heated material, enhancing the efficiency of the blow molding process.
