Abstract

The dependences of nonlinear parameters of resonant vibration of powder titanium sintered at 773 to 1473 K, on particle size and on porosity were studied. Quality of interparticle contacts in partly sintered titanium of porosity 0,05—0,4 was found to be increase with porosity and particle size, however after sintering at 1273 K and higher temperature these dependences are lost, that indicate of vanishing planar defects.
