“…For example, whereas full density was easily achievable starting with 3:1 Zr/B 4 C mixture, the maximum density achieved when starting with a 3:1 Ti/B 4 C mixture was only 92% of the theoretical density. 6 The microstructure of the 4:1 composition is significantly coarser and more faceted than the 3:1 or 3.5:1 compositions. This was attributed to the formation of a eutectic composition liquid.…”

A recently developed processing technique called transient plastic-phase processing (TPPP) is capable of the in-situ net-shape manufacturing of complexly shaped, fully dense, ultrarefractory composites at much lower (homologous) temperatures than those currently used. The viability of this technique as well as its advantages over the traditional processing routes has been demonstrated for the Ti-B-C and Zr-B-C systems. The resulting composites had higher than 99% density and excellent mechanical properties.

“…A seleção dos ligantes depende fundamentalmente da abrasividade do material a ser usinado. A combinação de alto ponto de fusão, alta dureza, elevado módulo de elasticidade, excelente condutividade elétrica e coeficiente de expansão térmica relativamente baixo, tornam o diboreto de titânio (TiB2) um importante material para aplicações de alto desempenho [8,12,10]. Estudos relacionados à sinterização de cBN utilizando alumínio como ligante relatam uma melhoria no desempenho do compósito quando é adicionada uma pequena quantidade de Alumínio entre 10-30%, permitindo otimizar as propriedades do compósito.…”

ResumoOs compósitos produzidos a partir de Nitreto cúbico de Boro (cBN) são utilizados nos processos de usinagem de materiais ferrosos, tais como, peças fabricadas a partir de ligas ferrosas, ligas a base de níquel e materiais ferrosos com dureza de 45 HRc. Os compósitos a base de cBN são produzidos sinterizando cBN e seus ligantes sob condições de altas pressões e altas temperaturas (APAT). O presente trabalho tem como objetivo a caracterização microestrutural dos compósitos nanoestruturados de cBN, processados sob altas pressões e altas temperaturas, com parâmetros de pressão de 6,6 GPa e 1800 o C e tempo de processamento cíclico e acíclico. Os compósitos produzidos foram testados na usinagem de aço 4140. Os resultados mostraram que uma melhor densificação e uma menor perda de massa dos compósitos durante a usinagem tem relação com os parâmetros de sinterização e com o tempo de processamento.

PROCESSING AND MICROSTRUCTURAL CHARACTERIZATION OF NANOSTRUCTURED COMPOSITES OF CBN FOR INDUSTRIAL METAL/MECHANICAL AbstractThe composites made from cubic boron nitrite (cBN) are used in machining of ferrous materials processes, such as parts made from ferrous alloys, nickel based alloys, and ferrous materials with a hardness of 45 HRC. The composites cBN base are produced by sintering cBN and its ligands under conditions of high pressure and high temperatures (APAT). This paper aims to microstructural characterization of nanostructured composites of cBN, processed under high pressure and high temperature, with pressure parameters 6,6 GPa and 1800 o C and cyclic and acyclic processing time. The composites produced were tested for machining steel 4140. The results showed the improved densification and less weight loss machining of composites is related to sintering parameters and processing time.

Sintered composites of WC-WB-W 2 B were prepared from B 4 C-W-WC powders using a reactive energization hot-pressing technique that initiated a solid state reaction between B 4 C and W. Below a WC mole fraction of 0.769 in the starting powder, WB and WC were formed according to the reaction B 4 C + 5W + xWC = WB + (1 + x)WC, while WB, W 2 B, and WC were produced above a mole fraction of 0.854. Densely sintered bodies were not obtained for pure WC. Composites of WC-WB-W 2 B obtained at WC mole fractions between 0.854 and 0.956 were fully consolidated, having high Young's modulus and Vickers hardness values, and a fracture toughness which were comparable to those of WC.
