General Motors-AISI AAC Advanced High Strength Steel Repairability Study Phase I Final Report Introduction The introduction of Advanced High Strength Steels (AHSS) to light vehicle body structure applications poses a significant challenge to organizations involved in the repair of vehicle structures. AHSS are typically produced by nontraditional thermal cycles and contain microstructural components whose mechanical properties can be altered by exposure to elevated temperatures. This temperature

In the article‚ “Sunken Steel Cages Could Save Coral Reefs”‚ Gaia Vince discusses that sunken steel cages may help restore endangered coral reefs. First‚ Vince explains how the steel cages are showing results for the endangered reefs. Carbon dioxide is above the level that it needs to be‚ and that is part of why coral reefs are going extinct. The metal cages do not fix that problem‚ but they appear to show results. The steel cages are connected to a long electrical cable that triggers a chemical

How do concrete and steel compare in the construction of large commercial buildings? Office buildings‚ Hotels‚ Sports Complexes‚ and other buildings have the purpose of bringing people inside. The goal is to keep occupants comfortable and safe‚ while keeping the cost associated withe the construction and maintenance of the building low. Both materials have advantages and disadvantages. However‚ when it comes right to it‚ the differences between the tow materials balance themselves out . There is

GROWTH OF THE STEEL INDUSTRY WHY THE INDUSTRY? The reason for focusing on this industry is that‚ Steel industry has become a major production and consumption market‚ with tremendous potential for growth after the reduction of the export tariffs from 15% to 5%. There has been a consistent rise in the prices and the demand expectations are growing rapidly for the coming years due to planned investment in infrastructure development‚ increased urbanization and growth in key steel sectors i.e.

Guns‚ Germs‚ and Steel Episode Three: Into the Tropics This episode was actually rather interesting. In general‚ it basically discussed how guns‚ germs‚ and steel have affected and influenced the shaping of African societies as it is today. Diamond’s main quest is to answer the question: why did the world become so unequal? In the mid-1600s the Europeans first arrive at the southernmost tip of South Africa. The southernmost tip of Africa and Europe are almost identical in latitude‚ with
