In situ synthesis mechanism of double core/rim structure Ti(C,N)-based cermets prepared by reactive hot pressing

Journal of Materials Research and Technology, 2022
In situ Ti(C,N)-based cermets with white core/gray rim and black core/gray rim structures were synthesized from a Co–Ti–C–TiN–W system. In addition, the reaction mechanism was explored.

An experimental investigation of chatter effects on tool life [PDF]

, 2009
Tool wear is one of the most important considerations in machining operations as it affects surface quality and integrity, productivity and cost. The most commonly used model for tool life analysis is the one proposed by F.W.

In situ synthesis and formation mechanism of ZrC and ZrB2 by combustion synthesis from the Co-Zr-B4C system

Journal of Asian Ceramic Societies, 2015
ZrC-ZrB2-based composites were prepared by combustion synthesis (CS) reaction from 10 wt.% to 50 wt.% Co-Zr-B4C powder mixtures. With increasing Co contents, the particle sizes of near-spherical ZrC and platelet-like ZrB2 decreased from 1 μm to 0.5 μm ...

On Measurement and Interpretation of Toughness Behaviour of Carbide Tools [PDF]

, 1981
The actual significance of any definition of toughness behaviour of carbide tools depends on the existence of an interrelation between the quality as defined and the occurrence of chipping and premature failure in cutting.

Dynamometric cutting tool

iPolytech Journal, 2023
The aim was to develop, manufacture and test a technically simple dynamometer for monitoring the cutting process during boring and turning. An S20R-SSSCR09 right-hand cutter was selected as a research object. To register the cutting force and vibration movements of the cutter tip in tangential and radial directions, the cutter was equipped with four ...
