Qualitative texture investigation of a maraging steel sample by neutron diffraction technique

Description

By means of the neutron diffraction technique the texture of a maraging steel rolled sheet have been determined. The measurements were performed by using a neutron diffractometer installed at the IEA-PI Nuclear Research Reactor, in the beam-hole n0 6. To avoid corrections such as neutron absorption and sample luminosity the geometric form of the sample was approximated to spheric and its dimensions do not exceed that of neutron beam. The texture of the sample was analysed with help of a computer programm that analyses the intensity of the diffracted neutron beam and plot the pole figure. (author)

Abstract (Portuguese)

A tecnica da difracao de neutrons foi utilizada na determinacao da textura de uma chapa laminada de aco do tipo maraging. As medidas experimentais foram feitas em um difratometro de neutrons instalado junto ao reator nuclear de pesquisas IEA-R1, no canal de irradiacao n0 6. A amostra foi confeccionada no formato aproximado de uma esfera cuja dimensao nao excede a do feixe de neutrons que e extraido desse canal e dessa forma correcoes devido a variacao de atenuacao dos neutrons e de iluminacao da amostra sao evitadas. Um programa de computador analisa a intensidade do feixe de neutrons que e difratada pela amostra e gera figuras de polos atraves das quais sua textura e observada. (autor)
