Fe, C 0.8 (wt%) steel, eutectoid transformation, normalised at 900ºC

Processing Normalised 900 ºC [...] Sample preparation Nital Technique Reflected light microscopy Length bar 400 μm / 100 µm Further information This steel is of the eutectoid composition. Once the temperature is lowered below the eutectoid temperature the steel becomes simultaneously supersaturated with both ferrite and cementite. A eutectoid transformation results (g to a + Fe3C). The resultant microstructure, known as pearlite, comprises lamellae of cementite (dark) embedded in ferrite (white). The platelets are parallel to each other and do not follow a specific crystallographic direction. Contributor Dr R F Cochrane Organisation Department of Materials, University of Leeds

Scrap Ferrite ex, my first gen 9 pokemon card, and first 3D card I've modeled in Blender.

It's been a lot of fun getting back into 3D. This one required me to do a little forced perspective to get the pose to be readable + exaggerated enough.

Mod:"It's late but here ya go. Never drawn all my babs together haha. Thanks everyone for the year. It was hard. Omg no more 😅."

Rhino the Toughest Warframe

Inspired by – Rudolph the Red-Nosed Reindeer

Original song written by – Johnny Marks

Rhino the Toughest Warframe,

Was for a Tenno quite slow.

But if you saw them don Ferrite,

You could even see them glow.

 All of the Grineer soldiers,

Tried to murder them with glee.

Their Ferrite took all the damage,

And made them all turn and flee.

 Then Captain Vor came to fight,

Looking for a romp.

He praised his beloved Queens,

Oh clem, it’s the Rhino Stomp!

 All of the Tenno love them,

When they find success, they cheer:

Rhino the Toughest Warframe,

You’re the one the Grineer fear!

Not quite studyblr pretty, but I'm proud anyway.

Fe, C 0.07, Mn 2.3 (wt%) steel, carburised at 950°C

Processing carburised 950°C [...] Sample preparation Nital Technique Reflected light microscopy Length bar 800 μm / 400 µm Further information After initial casting of this steel it was subject to a process known as carburisation. The metal is heated to above the ferrite-austenite transition in a carbon atmosphere. This establishes a concentration gradient and hence carbon diffuses into the steel. Usually the steel is then hardened by quenching. This produces what is known as a case hardened steel - with a hard surface (case) surrounding a tough core. The carbon gradient can be seen in the changing shade of the sample from left to right, with high carbon concentration at the left (surface) and hence a martensitic phase, changing to the lighter shade consisting of mostly ferrite.
