Hydrogen Embrittlement. The Silent Killer.

What do we know about Hydrogen Embrittlement (HE)?

A stealthy invader, hydrogen, infiltrates the steel, compromising its integrity and leading to unexpected failures.

Entry of Hydrogen into the Fastener: Occurs predominantly during manufacturing or galvanizing processes, where hydrogen finds its way into the steel lattice.

Diffusion of Hydrogen: Hydrogen atoms diffuse towards regions of high tensile stress within the fastener, driven by the stress gradients.

Hydrogen Segregation: They nestle in grain boundaries, inclusions, dislocations, and other macrostructural traps within the steel.

Reach of Critical Hydrogen Concentration: Accumulation of hydrogen reaches a critical concentration, setting the stage for potential catastrophic failure.

Prevention and Hydrogen Relief: Employing rigorous manufacturing practices and postproduction treatments to minimize hydrogen ingress and promote its escape.

Inspection Procedure: Employ meticulous inspection protocols to detect and measure ΗΕ, ensuring the reliability of the fasteners

In the Hermit Kingdom Loose Screws Opened the Path to Freedom

A border bristling with soldiers, where every step could be your last because of mines and fences sharp enough to slice the sky. This is the DMZ, a no-man’s-land splitting the Korean Peninsula into North and South.

Yet, in a twist that seems more like a scene from a suspense film, a North Korean man made it across — silently, unexpectedly, inexplicably. He was a former gymnast, they say, who used his skills to scale the formidable fence.

And then, the unbelievable part: the high-tech alarms, South Korea’s electronic eyes on the border, didn’t make a sound. The South’s military, faced with embarrassment, had to admit the breach. It turned out the culprit was a few loose screws — quite literally — in the sensor system, a flaw no one saw coming.

The tale begins on a crisp November morning when the man, whose life until then had played out under the watchful gaze of the North’s regime, decided to make a break for freedom. He crawled over that fence, and the alarms stayed silent, giving him a free path to a new life. South Korea’s soldiers, trained for the opposite of silence at this border, scrambled. The hunt was on.

How did he slip by? It was only later they found the sensors, their screws undone — a tiny oversight with enormous consequences. For a country that prides itself on vigilance against its unpredictable neighbor, this was more than a mishap; it was a moment of reckoning.

Questions flew like shrapnel: How could this happen? Who’s accountable? Can we make sure it never happens again? The military’s cheeks weren’t the only things burning. Their phones were, too, with calls for an explanation. They assured the public that every sensor is now under scrutiny, every screw tightened, every eye wide open.

This gymnast’s leap to liberty was rare, almost unheard of. Most who flee North Korea take a longer, no less perilous path through China. Yet, this man’s silent journey across the DMZ, under the moon’s watchful eye, is a stark reminder — sometimes, freedom’s call is so strong it can turn the world’s most dangerous borders into mere hurdles.

As South Korea tightens its screws, we’re reminded of the importance of the binding material in security and the fierce determination of the human spirit. One man’s dash to freedom underscores the countless untold stories still waiting on the other side of the fence.

Tesla Rival Rivian Recalled Nearly All ITs Vehicles

🪫 When the seemingly unnoticeable fails, catastrophe can strike. Rivian, an electric car company, found this out the hard way when they had to recall 13,000 vehicles due to a steering issue. The problem? An insufficiently torqued fastener. This tiny flaw can cause rare instances where drivers might have difficulty steering their cars and—in some bad cases—lose control entirely.

Rivian has only been around since 2020, so nearly all of the vehicles delivered are part of this recall; however, according to them, only 1% of these cars will experience symptoms from the faulty part. They’ve issued an email to customers apologizing for any inconvenience and assuring them that repairs will be made free of cost within 30 days timeframe. Rivian’s popular R1T pickup truck starts at $73 thousand while their SUV version R1S begins at $78 thousand, but with recent events like these, shares have fallen 📉 64% since earlier this year.
