Three ferrite/martensite dual-phase steels varying in the ferrite grain size (12.4, 2.4 and 1.2 um) but with the same martensite content ( 30 vol.%) were produced by large-strain warm deformation at different deformation temperatures, followed by intercritical annealing.
PREFACE Being a student of nineteenth and twentieth century architecture one finds that the Victorian Period was rife with confusion and endless debates over the preferred styles of architecture.
Direct-Reduced Iron. 27 Fastmelt takes DRI from the Fastmet process (that employs a rotary hearth reduction furnace to produce coal-based DRI) and converts the DRI to hot metal using the DC-arc Electric Ironmaking Furnace (EIF).

In this paper we report the maximum potential for cement substitution with secondary materials to reduce CO2 emissions globally (1.3 Gt CO2-eq. in 2018) and on a country-by-country basis.
Shielded metal arc welding (SMAW), also known as manual metal arc welding (MMA or MMAW), flux shielded arc welding or informally as stick welding, is a manual arc welding process that uses a consumable electrode covered with a flux to lay the weld.. An electric current, in the form of either alternating current or direct current from a welding power supply, is used …

Digital circuits. The parametron was a logic circuit element invented by Eiichi Goto in 1954. It was a digital computer element. Parametrons were used in Japanese computers from 1954 to the early 1960s, such as the University of Tokyo's PC-1 built in 1958, due to being reliable and inexpensive, but were ultimately surpassed by transistors due to differences in speed.
The ladle top slag floats on the surface of the steel in the ladle and has a profound impact on the inclusion population in the steel. Converter carryover slag – during primary steel refining in the BOS / EAF converter, slag-making additions are made to form a slag which absorbs impurities from the steel (such as sulphur and phosphorus ...

Professor Ravi Naidu is a global leader in contamination studies, studying agricultural and industrial impacts on the environment. His research has led to the implementation of policy directives for governments and new technology to manage and remediate polluted groundwater and soil, both in Australia and abroad.
Subaru's EE20 engine was a 2.0-litre horizontally-opposed (or 'boxer') four-cylinder turbo-diesel engine. For Australia, the EE20 diesel engine was first offered in the Subaru BR Outback in 2009 and subsequently powered the Subaru SH Forester, SJ Forester and BS Outback.The EE20 diesel engine underwent substantial changes in 2014 to comply with Euro 6 emissions …

The recovery of non-ferrous metals using the STEINERT EddyC and the sorting of light and heavy metals in small grain sizes using the STEINERT XSS-T is nothing new. But what is new is the option of using X-ray fluorescence to economically separate ultra-pure products down to a fine grain of 5 mm and recover zinc, brass and copper in their purest ...
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century. It has been described as "the ...
