The present paper comprehensively reviews non contact nondestructive testing (NDT) methods in use around the world for the solid materials.
(4) This kind of detection is only applicable to metal materials.
The laser ultrasonic detection technology has been applied very well in metal, composite materials and pottery.
However, ultrasonic detection frequency is relatively low and only suitable for detecting part of the materials.

Professional paper shows the general characteristics of graded materials, their previous industrial use and potential use of graded materials in the future.
Introduction Graded materials (FGM - Functionally Graded Materials) are in intensive use for last two decades.
The largest groups of graded materials are as follows: - bioactive graded materials, - tool steel with C, V, Cr and Ti gradients, - materials with self-lubricating ability, - graded materials with high temperature resistant surface layer. 2.
Properties of functionally graded materials Graded materials are very innovative product in the field of technology.
