'Vaporized' Steel From WTC 7
The photo above is a sample (showing what remained of part of a structural steel I-beam) depicted in the FEMA Building Performance Study (BPAT) Appendix C: A Limited Metallurgical Examination May 2002 and is believed to have come from the WTC 7 debris pile. According to Dr Steven E Jones, Appendix C of the FEMA 403 (BPAT), was the only properly peer-reviewed section of the entire paper.
The report states, 'Evidence of a severe high temperature corrosion attack on the steel, including oxidation and sulfidation with subsequent intragranular melting, was readily visible in the near-surface microstructure. A liquid eutectic mixture* containing primarily iron, oxygen, and sulfur formed during this hot corrosion attack on the steel. This sulfur-rich liquid penetrated preferentially down grain boundaries of the steel, severely weakening the beam.' ... 'The thinning of the steel occurred by a high-temperature corrosion due to a combination of oxidation and sulfidation. Heating of the steel into a hot corrosive environment ...that liquefied the steel. (emphasis mine). The severe corrosion and subsequent erosion are a very unusual event. No clear explanation for the source of the sulfur has been identified.'

*A eutectic is a mixture of two substances having a melting point lower than that of its individual components: In this case sulfur added thermite. https://en.wiktionary.org/wiki/eutectic
'FEMA appropriately called for further investigation of this finding, which the New York Times called “perhaps the deepest mystery uncovered in the investigation” (Killough-Miller, 2002). But the NIST report, in its section headed “Learning from the Recovered Steel,” fails even to mention either evaporation or sulfidation. ' (DR Griffin)
"A one-inch column has been reduced to half-inch thickness. Its edges--which are curled like a paper scroll--have been thinned to almost razor sharpness. Gaping holes-- some larger than a silver dollar--let light shine through a formerly solid steel flange. This Swiss cheese appearance shocked all of the fire-wise professors, who expected to see distortion and bending--but not holes.” -WPI
"One piece Dr. Astaneh-Asl saw was a charred horizontal I-beam from 7 World Trade Center, a 47-story skyscraper that collapsed from fire eight hours after the attacks. The beam, so named because its cross-section looks like a capital I, had clearly endured searing temperatures. Parts of the flat top of the I, once five-eighths of an inch thick, had vaporized.

“..fire and the structural damage . . . would not explain steel members in the debris pile that appear to have been partly evaporated in extraordinarily high temperatures.” -Dr. Jonathan Barnett, Professor of Fire Protection Engineering at Worcester Polytechnic Institute [
