    摘要： The present invention relates to a sintered body of titanium-based carbonitride alloy comprising hard constituents containing at least tungsten in addition to titanium in a binder phase based on cobalt. There are four distinctly different microstructural components, namely: A) cores which are remnants of and have a metal composition determined by the raw material powder; B) tungsten-rich cores formed during the sintering; C) outer rims with intermediate tungsten content formed during the sintering; and D) a binder phase of a solid solution of at least titanium and tungsten in cobalt. Toughness and wear resistance are varied by adding WC, (Ti,W)C, and/or (Ti,W)(C,N) in varying amounts as raw materials.

    摘要： A titanium-based carbonitride cutting tool insert with superior thermal shock resistance is disclosed. This is accomplished by sintering the material under conditions where the melting process is reversed. The melt forms in the center of the material first and the melting front propagates outwards towards the surface. This leads to minimal porosity and a macroscopic cobalt depletion towards the surface. The cobalt depletion, in turn, leads to a favorable compressive residual stress in the surface zone.

    摘要： The present invention provides a method for laser brazing a first member to a second member using a laser brazing head. The laser brazing head has means for generating a first laser beam and a second laser beam. The method comprises the steps of: arranging the first member in contact with the second member such that a junction is formed there-between; providing a filler material in the vicinity of said junction, and passing the laser brazing head along the junction such that the first laser beam melts the filler material to at least partially fill said junction to form a brazed joint. The second laser beam then effects a post heat treatment of the brazed joint.
