Metallography

Metallographic specimens provide the necessary detailed information about specific localities but they cannot give an overview about the overall quality of a material unless an inordinate number of samples are taken.

These solutions are important teaching aids and indispensable diagnostic tools; they are a simple, quick, effective and cheap way of evaluating the characteristics of a metal weld.

Enables more vibrant colours and use for high-end handcrafted titanium bicycle frames.
2L for cold etch and 4L for hot etch.
Cold etch is preferable although not critical.
Which Etch as per ASTM E 407 will be useful?

Impurities in and on raw materials and products can substantially enhance the properties of a welded material or weaken it to such an extent that it causes complete failure of the product. This article is designed to explore the application of impurities in welded metals and how to mitigate their undesirable effects.
