Hello, I had found an eBook on the internet on all about Steel.
Below is the link.

Chapter 2 talks about how industrial titanium was born of an advanced technology in 1948-high-purity titanium tetrachloride reduction under argon.
Vacuum arc remelting, control of embrittling hydrogen, plus the first titanium alloys and produced at high tonnages as a specialty metal.
Chapter 3 emphasizes on the important aspects of the story of structural titanium metal are unique in the annals of metallurgical history. How mysterious, fascinating, exciting, frustrating, unusual, expensive, lavish, vital, critical.
Chapter 4 is about titanium ore reserves are abundant and widely distributed throughout the world. So, in terms of contained titanium, the manufacture of titanium dioxide in the United States is about 15 times greater than the production of titanium metal.
Chapter 7 is about titanium melting, alloying, mill processing, and heat treating.
Ingot Melting: The principal product associated with the melting of titanium sponge is ingot. The process of melting titanium also is used to make castings and spherical powder and, more recently, to produce bulk metal from lightweight forms of scrap (eg. Turnings and grindings)
Present practice
Titanium ingot is the precursor form for most titanium mill products (the exceptions are the as-cast performs and the performs produced by powder metallurgy techniques). The steps required to make ingot include:
Chapter 9: End uses of titanium
“Light, strong, ductile, and corrosion-resistant” were the features that sold titanium offered from the beginning. “Light and strong” meant a higher strength-to-weight ratio than that possessed by aluminum and steel up to 550 degree Celsius. “Ductile” implied formability and toughness. “Corrosion resistance” signified maintenance-free aircraft eve on seawater-drenched carriers.
So, Steel ateial is a still-growing uses of titanium in the aerospace industry.
Reason for titanium use:
The element titanium in bulk metallic form is a relatively low-strength plastic solid intermediate density that is extremely reactive chemically.
Titanium also has low thermal and electrical conductivity and a weak paramagnetic response. The usefulness of titanium as an engineering material is related to its uniquely desirable combination of chemical, physical, and mechanical properties and to the ability to prepare high-strength, tough, and ductile alloys from the base material.
Titanium and its alloys are quite corrosion resistant in most common environment and even in some that very aggressively attack most other engineering metals. Oxidation reactions in titanium are insignificant.
Chapter 10: Titanium supply and demand and price trends
Despite the unusual history of titanium as a structural metal, it has much in common with its alternative construction materials. Viewed from this perspective, titanium’s turbulent first 30 years and the steadily emerging strength of its industrial markets fit the usual pattern of increasing stability based on ever-widening diversity and proportion of industrial uses.
