How does Forging Affect Grain Structure?
The important impliion about grain flow is that some mechanical properties vary with respect to orientation relative to grain flow. This fact is one of the major advantages of forging . This variation in mechanical properties can be exploited so that the actual product has superior properties in a critical direction relative to those expected from the alloy composition itself.
Aluminum Manufacturers Suppliers | IQS Directory
Aluminum emerged in the 19th century and became an exciting alternative to both steel and concrete. Aluminum tubing and aluminum plates are used to reinforce or replace aging structures. Visit this page to find aluminum tubing for your own company''s projects.
Metal Boats For Blue Water - Kasten Marine Design
A titanium structure having an equivalent strength to a steel structure will be approximately 40% lighter than the steel structure, and roughly 10% lighter than an aluminum structure. Since we know from experience that "form follows budget" the choice of materials for a boat''s structure ultimately comes down to a question of cost, which we will consider below.
CHAPTER 3: CRYSTAL STRUCTURES & PROPERTIES
