What is the Alpha case in Titanium?
The alpha case is a hard and brittle layer formed due to the reaction of Titanium with Oxygen at a higher temperature. 

What are the effects of the Alpha case on Titanium materials/end-products?
When subjected to repetitive or sudden load, crack initiation can occur at the alpha case layer leading to a material failure. The alpha case in Titanium implants is not desirable as it can cause an implant failure. 

What are the ways to avoid the Alpha case?
Titanium raw materials must be as per ASTM F136 & ISO 5832-3 standards. These standards suggest there is no possibility of Alpha case in the Titanium materials.
Processes such as machine milling, mechanical machining or chemical milling can remove this layer.
