DEVICE FOR RESEARCH micromechanical characteristics of solids indentation

摘要

The invention relates to measuring equipment for investigation and determination of mechanical properties of materials by application of mechanical stress claimed device comprises indenter and disposed within the housing the loading mechanism unit indentor probe loading force and displacement sensor of the indenter, where the indenter is kinematically linked to the loading mechanism loading force through the sensor, and the indenter loading mechanism is in the form of an electromagnet with a movable rod. Sensor loading force is designed as a strain gauge, which is rigidly fixed socket installation of replaceable indenters, and displacement of the indenter sensor includes a reflective diffraction grating arranged on the basis of the nest installation of replaceable indenters such a way that the direction of grooves of the diffraction grating perpendicularly to the axis of movement of the indentor and readhead comprising a laser and two photodetectors disposed on the housing and the device opposite the diffraction grating so that each of f otopriemnikov optically conjugate with the laser output through the reflective surface of the grating. 1 ZP f-ly, 3 Fig.
