In an era of rapidly changing technology, maintaining competitiveness is no longer achievable through physical assets alone. The value and success of modern organizations are measured not by their material resources, but by their potential of knowledge and capabilities.
SAE Engineering and Consulting Services was founded on this understanding: bringing the accumulated knowledge of the engineering disciplines — above all metallurgical and materials engineering — together with the needs of industry.
What We Work On
Our focus is metallurgical and materials engineering: establishing the relationship between a
part’s material, its manufacturing route and its service condition. The subjects we
work on are:
- Material and process selection: matching material and manufacturing method to the load,
the environment and the production volume, and verifying standard equivalents.
- Failure and fracture surface analysis: identifying the fracture mechanism, reading the
fracture surface, and combining microstructural and hardness evidence into one consistent root-cause
scenario.
- Manufacturing-related defects: distinguishing discontinuities originating in casting,
forging, welding and heat treatment, and proposing preventive measures.
- Conformity to standards: comparing test and inspection practice against the relevant
EN / ISO / ASTM documents.
- Technical content and training: the publication series below, and engineering education
applications.
SAE Technical Publications
19 technical notes are published free of charge on this site. Each one can be read in full on its own page
and downloaded as an A4 PDF (the PDFs are in Turkish). The principle behind the series is constant: the text
is original, the diagrams were drawn for these notes, and the bibliography consists of real book references
and standard numbers.
- Casting Technology — Gating and feeding, solidification, and telling shrinkage from gas porosity.
- Forging Technology — Grain flow, closed-die and flash systems, temperature window, forging defects.
- Aluminium Alloys — Series, tempers, precipitation hardening, hydrogen and oxide bifilms.
- Titanium Alloys — Alpha-beta metallurgy, alloy classes, microstructure selection, alpha case.
- Semi-Solid Forming — Thixotropy, thixo and rheo routes, laminar filling and heat treatable castings.
- Failure and Fracture Analysis — Investigation stages, fracture types, reading beach marks.
- Heat Treatment of Steels — CCT, hardenability and Jominy, quenching, tempering, case hardening.
- Steel Selection and Equivalents — EN/AISI/DIN equivalents, carbon equivalent, section effect.
- Fatigue and Life Estimation — S-N curves, mean stress, notch effect, rainflow and Miner's rule.
- Metallography and Specimen Preparation — Sectioning, polishing, etchants, artefact or reality.
- Welding Metallurgy — HAZ and t8/5, cold and hot cracking, defects, qualification.
- Corrosion and Protection — Galvanic series and area ratio, pitting, PREN, SCC, cathodic protection.
- Hardness Testing — Brinell, Vickers, Rockwell, portable methods, conversion limits, case depth.
- Non-Destructive Testing — Choosing PT, MT, ET, UT or RT; probability of detection.
- Fracture Mechanics and Toughness — K, CTOD and J, critical crack size, damage tolerance.
- Surface Treatments and Coatings — Coating families, effect on fatigue, hydrogen baking.
- Tribology: Wear and Lubrication — Wear mechanisms, Stribeck curve, lambda ratio, pairing.
- Powder Metallurgy and Additive Manufacturing — Powders, sintering stages, porosity, HIP.
- Mechanical Testing — Tensile, compression, bend and Charpy testing and what they mean.
How the Notes Are Written
Each note is written after reviewing the fundamental books and the standards in force; the mistakes seen
most often in practice are condensed into “symptom – root cause – prevention” tables,
and an original diagram is drawn for the mechanism being explained. Every number must be
traceable to its source; what cannot be verified does not enter the text. The notes cross-reference each
other, so the series can be read as a single body of work.
Who They Are For
- Engineers and technicians working in manufacturing and quality,
- Teams performing failure investigations, supplier assessment or material selection,
- Students of metallurgy, mechanical and manufacturing engineering.
Our Approach
