This paper presents a measurement method of the thermal dissipation in metallic samples submitted to a plastic strain. Its interest is to extend the field of experimental investigation of the irreversible plastic transformations. The method is applie

The plasticization induced by the shot-peening treatment is an exothermic transformation. One can imagine to link the induced residual stress level to the thermal behaviour of the sample during the treatment or, at least, to propose some means of pro

The cathodoluminescence (CL) emission arising from the indentation of an MgO single crystal cleaved along (100) faces is investigated by scanning near-field cathodoluminescence microscopy (SNCLM). This technique is performed with a hybrid instrument

We describe a new calibration method for lateral contact stiffness using modulated lateral force microscopy, a technique that offers some advantages with respect to the more classical friction force microscopy currently used for characterizing the fr

A new set-up for cathodoluminescence (CL) studies is described. It combines a scanning near-field optical/force microscopy (SNOM/SFM) with a scanning electron microscopy (SEM). This hybrid instrument allows one to image a sample conventionally by SEM

Very small temperature variations are quantified by a statistical treatment of standard infrared equipment images. This procedure determines the signal amplitude value, comparing the noise and the noisy signal dispersions characterized by their varia

Thermoelastic stress analysis is a full-field stress measurement technique complementary to local techniques like strain gages. Generally, the heat transfer inside the material is neglected with respect to the frequency of the cyclical loading. An ad

We present here a preliminary study concerning a multi-wavelength pyrometry method. This technique may be useful for temperature measurements on materials of unknown, selective, rapidly varying emissivity. From a (simultaneous) measurement of the the

FPA infrared cameras are presently at a fast development stage, owing to the rapid increase of the computers performances but, up today, only a few works have dealt with the characterization of such equipments. We present here the results of our firs
