Maraging steels are a class of ultra high strength steels of special importance due to their extremely high mechanical strength and good toughness. In this work, the effects of the solution annealing temperature on the mechanical properties of the maraging 300 steels were evaluated, in order to maximize the toughness without considerable detriment...
Some strategic sectors of the economy require that the raw material of their machines and equipment have mechanical properties that satisfy their use. Maraging steel is a material of great concern since it is necessary to have a high mechanical resistance associated with high fracture toughness. The traditional tests to determine the fracture tough...
– Muito se tem estudado sobre tratamentos térmicos dos aços maraging, em especial da classe 300, com o objetivo de melhoria das propriedades mecânicas. Neste trabalho, amostras do referido aço foram submetidas a dois tratamentos térmicos seqüenciais de solubilização: um a 1000 – 860 – 820 °C e outro a 1000 – 820 °C. Foram realizados ainda tratament...
Maraging 300 belongs to a family of metallic materials with extremely high mechanical strength and good toughness. Some works have been published about aging temperatures that improve ultimate strength resistance with acceptable toughness levels in this steel family, where the prior austenite grain size obtained by different solution annealing temp...
SiAlON matrix composites were prepared from a precursor reaction mixture of α-Si3N4, AlN, Al2O3 and Y2O3 powders and reinforced with different proportions of elongated SiAlON particles obtained by combustion synthesis. Green cylindrical specimens were consolidated by slip casting from well dispersed suspensions. The dried samples were densified by...
For several decades, ceramic matrix composite have been attracted attention in advanced structural and tribological applications. Advanced structural ceramics are presently used in diverse tribological applications such as tips for ballpoint pens, precision instrument bearings and cutting tools inserts. Design and selection of ceramics for these ap...
