6 A D V A N C E D M A T E R I A L S & P R O C E S S E S | O C T O B E R 2 0 1 7 FEEDBACK AUTOMOTIVE METAL MARKET WORTH $84.66 BILLION IN 2016 The global automotive metal mar- ket was worth $84.66 billion in 2016, according to a new report from Grand View Research Inc., San Francisco. Growing demand for vehicles coupled with abundant raw material availability are boosting international growth. Also, government efforts to enhance the manufacturing capabilities of emerging economies is anticipated to positively affect the market, say analysts. The sec- tor has been witnessing significant de- velopment in terms of materials, as well as technologies used to produce vehicle components. Further, new technologies including 3D printing are being used to produce large metal parts. Steel dominated the global mar- ket with a revenue share of 66.6% in 2016, although aluminum and magne- sium are the fastest growing materials in the automotive industry. The afford- ability and superior properties of new steel grades, including advanced/ultra high strength steel, are likely to posi- tively affect its utilization in the next eight years. Steel is also considered to have high recycling efficiency. In addi- tion, End of Life Vehicles (ELV) regula- tions in Europe, Japan, South Korea, and India are expected to propel the use of steel in the coming years. Magnesium is likely to witness the fastest CAGR of 8.4%, in terms of PIONEERS NOT RECOGNIZED IN NEWS STORY I enjoy keeping up with what is go- ing on in our professional community by reading AM&P each month. In the July/ August issue, there is a news item on page 9 about researchers at Shenyang University “…radically increasing the hardness of nanograined metals using electrodeposition and annealing.” This is not news. It has been done for years based on the pioneering work of Chris Schuh and colleagues at MIT who first showed that thermodynamic stabiliza- tion of nanograined metals was possible. Perhaps the new angle from the group at Shenyang is the tuning of hardness by varying grain size, but the piece reads as if they were the first group to create sta- ble nanocrystalline metal films. I realize this is a short news piece and there is not the space for rigorous citing of prior work. But it does draw into question the technical rigor with which pieces are reviewed when a story like this is advertised as a new advance, when there is a significant body of pub- lished prior work. Michael Dugger ERRATA —In “Additive Manufacturing for Aerospace Applications—Part I” (July/ August 2017), the AMS specifications be- ing developed for the AM process are from SAE’s Aerospace Materials Divi- sion Technical Standards Committee, not ASTM as first reported. The Ameri- can Welding Society’s (AWS) Committee D20 on Additive Manufacturing and The American Society for Testing and Mate- rials’ (ASTM) Committee F42 on Additive Manufacturing Technologies also have ongoing efforts in this area.—Eds. MARKET SPOTLIGHT Send letters to frances.richards@asminternational.org. Courtesy of Grand View Research Inc. revenue, from 2017 to 2025 due to low specific weight, better elongation, 20- 30% less cycle time, and ease of casting compared to other metals. Magnesium alloys have been witnessing signifi- cant development in terms of use in the powertrain, chassis, and exterior parts. Aluminum is also experiencing sig- nificant growth due to its light weight and high recyclability. Aluminum can absorb twice the crash energy as com- pared to mild steel and provides weight reduction of up to 50%, which is expect- ed to propel its demand. Body structure was the dominant automotive usage in the 2016 market and its revenue is expected to grow 4.5% by 2025. Ease of maintenance and repair of stamped metals parts and high recyclability as compared to plas- tics and composites add to its demand. Suspension accounted for 18.1% share, in terms of volume, in 2016. Numer- ous manufacturers are shifting toward lightweight products such as aluminum and magnesium in order to reduce ve- hicle weight.
