Toured the Dangote Refinery in Lekki, Lagos State, Nigeria, at the invitation of Dangote Group President and CEO @AlikoDangote ahead of our groundbreaking ceremony for the Dangote East African Refinery in Lamu, Kenya, next week. The refinery in Nigeria is a massive investment with a crude oil refining capacity of 700,000 barrels a day and produces more than 100 million litres of petrol, diesel and aviation fuel every day. The company has built 120km of sea cables to move crude from ships to the refinery. This huge achievement is a testament of what African governments, investors and financial institutions can do together. The refinery whose construction we launch in Kenya next week will be bigger. It will transform the petroleum sector in our country and region, providing fuel reliability and security, scaling up industrialisation and creating 60,000 jobs. When the refinery is completed, spin off industries will emerge, including the production of fertilisers, chemicals, and packaging.

All thanks to @dormanlong1949 #DORMANLONGENGINEERINGLIMITED for having 3M( Nigeria Institute Of Metallurgical, Material and Mining Engineering) a subdivision under the Nigeria Society Of Engineers (NSE) on the Professional Industrial visitation Indeed it was a great session 👷🏽💚

Damn @SympLySimi you can’t stop giving me goosebumps with that voice 😩💚🎉

I’ve been quiet… not absent. I was building, protecting, and embracing the greatest blessing of my life. God gave me more than I prayed for a woman who became a mother of three, and three kings to call my own 👑👑👑 My world. My responsibility. My legacy. Alhamdulilah! ✨

Microstructures in Steel: Pearlite vs Bainite vs Martensite 1. Pearlite What it looks like: • Alternating lamellae (layers) of: • Ferrite (α-Fe, soft) • Cementite (Fe₃C, hard) Key features: • Forms at ~727°C (eutectoid temperature) • Diffusion-controlled transformation • Can be: • Coarse pearlite → slow cooling → wider spacing • Fine pearlite → faster cooling → thinner lamellae Properties: • Moderate strength and hardness • Good ductility 2. Bainite What it looks like: • Feathery or acicular (needle-like) structure • Mixture of ferrite + very fine carbides Types: • Upper bainite (higher temp): feathery, carbide between laths • Lower bainite (lower temp): finer, carbides within ferrite Key features: • Forms between ~250–550°C • Partially diffusion-controlled Properties: • Higher strength than pearlite • Better toughness than martensite 3. Martensite What it looks like: • Needle-like / lath / plate structure • Highly distorted lattice (BCT: body-centered tetragonal) Key features: • Forms by rapid quenching • Diffusionless (athermal) transformation • Supersaturated carbon in iron Properties: • Very high hardness and strength • Very low ductility (brittle unless tempered) #metallurgy

From a materials science perspective, the pillar’s resistance is due to: •Thermodynamically stable passive film (δ-FeOOH) •Phosphorus-assisted passivation kinetics •Heterogeneous microstructure aiding film adhesion •Mild atmospheric exposure (no chloride-driven breakdown) #metallurgy

Which one of the following is a ferrite stabilizer in steels? A. Ni B. Cu C. Cr D. Mn
